Important: Installation & Flushing

  • Isolate water and power (where fitted), then release pressure before servicing.
  • Check serviceable housings, including pre-assembled units, and remove shipping wrap. Keep permanent mesh, end caps and seals intact; do not dismantle sealed cartridges. Refit correctly and check for leaks.
  • New carbon releases dust that can block taps, aerators, strainers, downstream filters and other equipment.
  • At first use and after carbon replacement, route flushing water directly to a bucket or open drain, bypassing downstream equipment via the manufacturer's approved flushing connection.
  • Flush until clear, for at least the manufacturer's specified time or volume. Do not drink the flushing water; stop and contact H2O Warehouse if particles persist.
  • Where an RO membrane is fitted downstream, protect it using the model's separate-prefilter or assembled-system flushing procedure. Do not improvise bypasses or run pumps dry; complete membrane and system start-up flushing.
  • Clear water is not proof of drinking-water safety; follow all feed-water, disinfection and commissioning requirements.
